After a restart in July 2022, the LHC again delivered Pb collisions at the record energy of √s_NN= 5.36 TeV for a few hours on 18 November 2022. This first test of Pb-Pb collisions is an important step for the ALICE experiment to optimise and prepare the data taking and compression for the Quarks and Gluons Plasma (deconfined state of nuclear matter) programme in the 2023 Pb-Pb Run.
